Given numbers are 798,418,116,155,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 798,418,116,155,781 is 5602909620.
Find LCM of 798,418,116,155,781 with Prime Factorization
| 2 | 798, 418, 116, 155, 781 |
| 11 | 399, 209, 58, 155, 781 |
| 19 | 399, 19, 58, 155, 71 |
| 21, 1, 58, 155, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 19 x 21 x 1 x 58 x 155 x 71 = 5602909620
Therefore, the lowest common multiple of 798,418,116,155,781 is 5602909620.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
798 x 418 x 116 x 155 x 781 = 4684032442320
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
418 : 1, 2, 11, 19, 22, 38, 209, 418
116 : 1, 2, 4, 29, 58, 116
155 : 1, 5, 31, 155
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,418,116,155,781, is 1.
Now, the common factors can be found like this.
798:2x 3x 7x 19
418:2x 11x 19
116:2x 2x 29
155:5x 31
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 11x 19 = 836
Therefore, the value for common factors is 836.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 4684032442320/(1x836)
LCM = 4684032442320/836
LCM = 5602909620
Thus, we can understand that the LCM of 798,418,116,155,781 is 5602909620.
